reproducing the possible bug:
- cd examples/echo
- cmake . && make
- ./echo_server (terminal 1) and ./echo_client TEST (terminal 2) and ./echo_client TEST (terminal 3)
error message related to possible bug:
```
Assertion failed: (client->is_accepted || outgoing_msg->type == NBN_CLIENT_ACCEPTED_MESSAGE_TYPE), function GameServer_SendMessageTo, file nbnet.h, line 5498
```
suggested fix if this is indeed a bug:
- add `|| outgoing_msg->type == NBN_CLIENT_CLOSED_MESSAGE_TYPE` to assertion
* Fix rpc build with other examples
CPP_COMPILE is an option, a cache variable, thus regular unset() is not
working for it since it tries to unset the scope variable.
This causing cmake to skip compilation of rpc.
Unset CPP_COMPILE from CACHE to make it work as intended.
* Fix compiler flags with build targets
Currently tests, soak and examples are build without extra flags,
because add_compile_options is specified after defining build targets.
From add_compile_options() docs:
Adds options to the compiler command line for targets in the current
directory and below that are added *after* this command is invoked.
* Pass debug callbacks as struct
Fixes:
warning: ISO C forbids conversion of function pointer to object pointer
type
* Move global variables under NBNET_IMPL
Nb net could be included multiple times, to prevent creation of global
variables in each file move them under NBNET_IMPL.
Also use designated initializer to initiate a driver structure to
remove warnings about partial initialization. Designated initializer
would initialize other members to zero.
* Resolve unused variables warnings.
Cast unused function arguments to (void) to suspend warnings.
* Resolve signed vs unsigned warnings
Remove unnecessary lt 0 checks and sync types to remove signed vs
unsigned warnings.
* Resolve string related warnings
Fixes:
nbnet/tests/string_tests.c:18:9: error: ‘strncpy’
output truncated before terminating nul copying 5 bytes from a string of
the same length
[-Werror=stringop-truncation]
18 | strncpy(res + pos, b, len_b);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
nbnet/tests/string_tests.c:24:9: error: ‘strncpy’
specified bound depends on the length of the source argument
[-Werror=stringop-truncation]
* Resolve function defined but not used warnings
Mark GameServer_GetClientCount() as inline.
* Attempt to fix warning in ASSERT_VALUE_IN_RANGE
In case when value in unsigned type and min is 0, this commit just
obfuscates types, maybe there's better solution.
Fixes:
warning: comparison of unsigned expression in ‘>= 0’ is always true
[-Wtype-limits]
* Ensure that read len is less than word size
In release mode(-DCMAKE_BUILD_TYPE=Release) tests returning following
error:
nbnet/tests/../nbnet.h:2272:9: error: ‘memcpy’ forming offset [4, 7] is
out of the bound s [0, 4] of object ‘word’ with type ‘Word’ {aka
‘unsigned int’} [-Werror=array-bounds=]
2272 | memcpy(bytes, &word, length); |
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
Add check to verify that length is less than Word size.
* add -Wno-unknown-pragmas flag

C99 functions declared with an empty parameter list may accept any
number of arguments. Add a void parameter list to the declaration and
definitions of csprng_create to indicate that they accept zero
arguments.
